Huge Rocket Launch

[Azarooroo]

Fast, cool. Wonder what happened to launch trailer though?

cooool

"Q booster staging at 45K ft. to a P motor (~6x the thrust of a cruise missile booster)"

Yeah, I don't think so. Tomahawk lifts off at a weight of 3200 lbs.

@FelixA9 This is what i heard:

"I think it was used to boost a UK Cruise Missile. No US missiles use CTI technology. I heard this from Anthony Cesaroni...

Because the BGM-109 is tube launched, a thrust to weight ratio of 10:1 is not necessary. CTI with a military O motor in the same casing produces around 39,000 Ns of impulse or about 19,000 lbs of thrust for a 3-4 sec burn, or about 5,000 lbs of thrust, giving a thrust to weight ratio of about 2:1

Nice soft loft out of the launch tubes."

and this is legal why?

[drxcrime]

Why the hell should it not be? Do you know anything about rockets? At all? Oh ok, then you're not aware of how insanely difficult it would be to turn one into a weapon. Believe it or not, it has been shown to be more cost effective to build a missile out of a radio controlled airplane. Not to mention the level of permit you have to have in order to be able to use large motors like this (See Tripoli Level III certification, which is not easy to get).

@cortorboch12

Because he's busted his ass, gone through cleareances/classes/technical certification. I have a feeling you don't, so let me explain something. That rocket is not capable of carrying a meaningful payload, and is not dangerous when launched in a properly wavered site...

On the other hand, I could build an air assist mortor out of shit from the hardware store that could carry a 10-15 pound warhead for half the price, and no record keeping..

That's why...cause it's not dangerous.

Awesome and a shame it didn't have a rocket cam. Best rocket cam video for a private rocket is the sledgehammer vid. Does anybody know good sodium perchlorate as a propellant. Why sodium? Because this you can make from normal salt. Cheers

[nicksynnz]

a systems failure of course. Getting a rocket to space is one thing, putting it into orbit is a thousand times more difficult and you need guidance for that. If that vid was time correct the booster did not ignite the second stage.

[MrWombatPPC]

you should have shown the wreckage.

[Roncace]

failure launch?

[prostreetsporty]

the reasone it wouldnt go much more then 100k is mainly the drag was design was not optimal for drag. Also another huge factor is getting the proper optimal mass to get the most altitude.

[r0ck3tsm0k3]

@prostreetsporty Most P motors alone have been going to 75 - 100K. A P motor off a Q? Seriously what was overbuilt in this rocket? I know that spiral wound fiberglass is usually pretty darn heavy, was that a factor? Optimal mass for rockets this big has to usually be basically zero mass after the motor case and airframe. I mean this is 20+ seconds of burn time in here.

Not to take anything away from their work, great looking rocket. But I wonder if it really only will do 100K...

[r0ck3tsm0k3]

how does a Q to a P only go to 100,000 feet?

[superskullmaster]

Yea I would think it would at least match spaceship one with over 10,000lb of thrust on a 560lb rocket

[r0ck3tsm0k3]

It should hit space if designed with good mass fractions. Or at least 200,000 feet.

Nice up
